Windows 7 was released to manufacturing on August 6th and to public on October 22nd and now it seems that Microsoft has started working on the first Service pack for Windows 7.
Rafael @ Within Windows has found something interesting regarding SP1 for Windows 7.
Similar to previous external beta service pack rollouts, Microsoft has enabled – via updates you already installed – a beta 'candidacy check' within its Windows Update software.

Just like Windows Vista, a registry key and value pair need to be added prior to being authorized to download the new software.
Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Win7SP1
Value: SPORTM (REG_SZ)
Data: Unknown (likely a server-side checked GUID)
The external Windows 7 SP1 testing should commence soon, if it hasn't already.

Windows 7 for end user, like me, seems working really stable and fast, even on pretty crappy hardware. I hope that SP1 will make things even better.

So Vishal, am I supposed to add this to my registry as there is nothing at all that looks remotely like the registry key as shown above, in fatc, nothing at all says WIN7 at all? I am using the legal W7 that was released through Microsoft if that helps? Oh God, I wish I knew more about computers? LOL.

Woah, so its now Windows 7 SP 1, will there be any SP 2 now or straight to "Windows 8"? (oh gosh too many Windows programmers will find it difficult to migrate to new one)

I guess it is only coicidential (sp?) that they start working on a service pack right after if not during the release of Windows 7. Just like they did for 7 during Vista.

They started working on sp1 even BEFORE release of Windows 7. One of leaked builds contained "sp1" in build tag.

Just to add one little correction...Windows 7 officially RTM on July 13th as that is the date the RTM-candidate build 7600.16385 was unanimously signed off as gold
